Box 2.31Angiograms and feet of two diabetic patients

Image ch2fb31.jpg

Angiogram: A fine tube is inserted in the femoral artery in the groin and passed into the lower aorta. After a radiopaque dye is rapidly injected, a series of X-rays is taken. The background bone and muscle are removed from the pictures digitally so only appear as ‘ghosts’.

Left: The angiogram and foot of Clinical Case 2.4. Angiogram was normal showing absence of macrovascular disease. The ‘dinosaur bite’ (ulcer), towards the heel, was the result of a neuropathic foot.

Right: The angiogram and foot of a 65-year-old diabetic smoker. Angiogram was abnormal showing macrovascular disease. Very little dye entered the profunda femoris arteries and at point Image dclccA.jpg her femoral artery had been surgically replaced by a vein that runs to the popliteal artery Image dclccB.jpg . Blood flow to the toe was minimal causing a typical diabetic ischemic toe.
